Smart light switch with temperature sensing
A smart light switch includes a control block and heat generating components such as a light actuator, a processor and memory, a data communications module, and an environmental sensor. The processor is operable to receive as an input a measured temperature value from the environmental sensor and a power consumption value from the of heat generating components. The processor is operable to select a temperature offset value from a dataset of temperature offset values that is stored in memory. Each temperature offset value stored in the dataset of temperature offset values is associated with a potential combination of power consumption inputs. The processor is further operable to determine a calibrated temperature value from the measured temperature value adjusted by the temperature offset values selected from the dataset of temperature offset values.
